I personally think once a year is not enough. Every 6 months might be better. Also people already spend a lot during December that they might not prioritize donating to KDE.
For those complaining… Well I don’t know what to say to them. Such a big complex software which is 100% free should be allowed to remind us that they need money.
Don’t forget they said it’s running as a daemon specifically so you can easily disable it if it triggers you so much.
True but also free service and fun to play with.
